Plan your service

From a door-lock concern to the appropriate lock service.

1. Describe the lock issue

Provide the vehicle make, model, year and service location. Explain whether a key is lost, the door lock is damaged or hardware has already been replaced.

2. Review rekeying or replacement

Ask whether the existing cylinder can be configured to a different key or whether compatible hardware is required. Mention any separate electronic-key concern.

3. Confirm and check operation

Have identification and proof of ownership or authority ready. Agree the scope and price before work and check the serviced lock with the technician afterward.

Common questions

Before you book

Does car door-lock rekeying delete an electronic key?

No. Mechanical rekeying alone does not remove an electronic key from the vehicle’s authorized-key list. Tell us about lost electronic keys so the available security-system procedure can be reviewed separately.

Can every car door lock be rekeyed?

The answer depends on the lock design, condition and compatible parts. Send the vehicle details and explain the issue so the team can review rekeying and replacement options.

What should I send after a lost car key?

Include the make, model, year, location and details of the lost and remaining keys. Say whether your concern is mechanical door access, starting authorization or both.

About SherlockLock car lock rekeying

Mechanical lock work and electronic key authorization are different.

SherlockLock reviews car door-lock rekeying requests in Boston and Greater Boston after lost keys, lock damage or hardware changes. The existing cylinder and vehicle-specific parts determine whether rekeying or replacement can be offered.

Changing the mechanical key that operates a door does not by itself remove an electronic key from vehicle memory. Explain both concerns if they apply. Our team reviews the exact vehicle, lock condition and remaining keys before confirming compatible options, availability and pricing.
